Mastering Cabinet Door Sizing: Formulas and Trade Secrets
This Cabinet Door Size Calculator is designed to eliminate the complexity of cabinet construction math. Whether you are ordering new doors or cutting them yourself, precision is everything. Our tool uses industry-standard formulas to instantly convert your cabinet opening measurements into the precise finished door sizes required for various installation types.
Full Overlay and Frameless Cabinets
Full overlay doors create a clean, modern aesthetic by minimizing the visible cabinet face frame. This style is standard for frameless (European-style) cabinets. The calculation is straightforward: we add the required overlay amount to both the width and height of the opening. For double doors, the required door gap is subtracted from the total width before dividing by two.
Partial Overlay (Face Frame)
Partial overlay is the traditional method for face-frame cabinets, where a portion of the frame is visible. The calculation depends on whether your door overlaps the opening by a consistent amount (e.g., 1/2" or 3/4"). This tool handles these calculations accurately, ensuring your reveals are consistent across all door and drawer fronts.
Inset Door Measurements
Building inset cabinet doors requires the highest level of precision. Since the door sits *inside* the opening, the calculator must subtract the necessary door gap (or margin) from all four sides. This ensures the door can swing freely without rubbing the cabinet frame, giving you that high-end, furniture-quality fit.
Need Component Cut Lists?
Once you have the finished door size, the next step is breaking it down into component parts (stiles, rails, and panels). If you are building Shaker or raised-panel doors, please use our free and powerful 🛠️ Cabinet Door Cut List Software to instantly generate your material list.
